The small fork tail ( Furcula bifida ), sometimes also referred to as the aspen fork tail , is a butterfly ( moth ) from the family of toothed spinners (Notodontidae).
features
The moths reach a wingspan of 35 to 45 millimeters. They have whitish forewings with a gray central band. This is clearly bordered by black lines and, in addition to the larger wingspan, forms the main difference to the similar fork-tailed species. The hind wings are gray-white in color. The caterpillars have a light green color and a brown, yellow-edged back drawing. This drawing on the back is triangular in the middle, often narrowed or interrupted at the end. The abdomen, which tapers to a point, ends in a tail fork with two long tips, which gave the species its name.

- Birch forktail ( Furcula bicuspis )
Way of life
The caterpillars feed on the leaves of the aspen ( Populus tremula ) and the foliage of the poplars ( Populus ) and willows ( Salix ). The overwintering takes place as a pupa , which occasionally lies over several times.
Flight and caterpillar times
The nocturnal moths usually fly in one, sometimes in two generations, mostly from mid-May to the end of June. The caterpillars are found in July and August.
